MAGAZINE FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 290,529, dated December18, 18553.

Application filed January :2, 1860.

To all whom it Hwy concern:

Be it known that I, ANDREW BURGESS, of Owego, county of Tioga, State ofNew York, have invented a new and useful Improvement in MagazineFire-Arms, of which the following, in connection with the accompanyingdraw ings, is a specification.

This invention relates to magazine or brcechloading fire-arms; and itconsists in modifications of the reciprocating breech and lockingdevice, together with other combinations of magazines and parts,hereinafter more fully set forth and described.

, Similar letters of reference indicate corre sponding parts. c

Figure 1 represents a sectional side elevation of the arm. Fig. 2 is asectional plan view from the top; Fig. 3, the magazine and carrier stopdetached, and Fig. 4, a section through the frame, showing the face ofthe breech-bolt and modification of loading device, the arm being turnedon its side in position for loading. Fig. 5 represents a side elevationof a portion of this arm, showing the locking-shoulders H ll and theslot extending back from between them. Fig. 6 is a plan View, partlysectioned, showing the top of the locking-brace and its shoulders I) bin the unlocked position, and in dotted lines the position brace B takesas it looks the breech and cams forward the bolt.

F is the frame of the arm; B, the breech piece or bolt, ll, thelocking-block; f, the firing-bolt, and T the loading trap -or gate. Thisgate, as shown in Fig. 1, also serves as a carrier. A hollow bolt, 15,is fitted to reciprocate in the frame F. A swinging block, 15, hollowedto receive the firing-pin, having a handle, by which to move the bolt,is fitted into said bolt, and pivoted near its forward end, and saidblock B has alocking-shoulder, b, to engage correspondingloekingshoulders, H H, in the frame. It has also an inclined part, b, atits-rear, near its handle, and a doubleinclined projection, e, opposite.The firing P and the ejecting-stud e is inclined at its rear, as shownin Fig. 2. This arm, as shownin Fig. 1, is provided with twomagazines-one under the barrel and one in the rear; but either or bothcan be omitted without material change in the having the usual spiralspring, is pro-- bolt system above described. The rear magazinc isprovided with a detent, d, which is turned to engage and stop thecartridge by a spring, said spring being controlled by a projectingstud, p, to prevent said detent from engaging the forward part of thecartridge. This detent is turned back to disengage and release thecartridge by the projection f of the firing-pin. The. double-cam stop (1looks the cartridges to hold them firmly in the magazine, as shown inFig. 1, or releases them when turned back, as shown in dotted lines insame figure, and then also looks the carrier up to position, also shownby dotted lines.

The bolt B is provided with a spring, S, to prevent the cartridge in theforward magazine from entering upon the carrier until the breech isdrawn open. A. modification of said spring S is shown as a spring-studin Fig. 4, and a depression is made in the frame at S to permit saidstud S to be depressed by-the gate or trap T, which is here placed onthe side of the arm.

As cartridges of different manufacture vary in the thickness of theirheads, those with copper shells and inner primer especially beingthinner in the center than those made of brass, and having primersinserted from the outside, much trouble has been caused by using thesevarious kinds in the same arm, as the thinner heads swell, and sometimesburst at edge when the breech is made free enough to admit the thickerheaded cartridges. To avoid this and permit the use of these variouskinds with safety, I dish out the face of the breech-piece, making aconcavity to admit the rounder or raised center of the thicker-headedcartridges, so that only the outer edges of the breech close tightly onthe thiirheaded ones, there being little or no danger of their burstingtoward the center, while their swelling in the center is unimportant,this kind not being reloaded, and the thick shells are fully supportedby the breech, the thin edges of the head allowing the breech to closelysupport .them toward their center.
